Description

Technical Field

[0001] This invention relates to the field of wire harness cutting technology, and more specifically to a wire harness processing and cutting device. Background Technology

[0002] A wiring harness is a group of service equipment that provides services to a certain load source group, such as trunk lines, switching devices, and control systems. The basic research content of traffic theory is to study the relationship between traffic volume, call loss, and wiring harness capacity. Therefore, the wiring harness is an important basic concept in traffic theory. A wiring harness is a group of metal wires and cables bundled together, which connects the signals and power between the equipment. It is the wiring component that connects various electrical devices in the automotive circuit. It consists of an insulating sheath, terminals, wires, and insulating wrapping materials. During the processing of the wiring harness, it is cut to the required length according to the length required for use.

[0003] Currently, the assembly of electrical equipment involves wire harnesses of various lengths and sizes. During the cutting process, workers need to fix both ends of the wire harness before cutting it with a cutting blade. However, this cutting method, because the wire harness is fixed at both ends before cutting, may cause the internal copper wires to be stretched or even broken due to tension, thus affecting the conductivity. The tension generated by fixing the ends of the wire harness will cause the wire harness to spring back at the moment of cutting, resulting in burrs or bevels on the cut surface, affecting the sealing of subsequent crimping, and thus reducing the quality of the wire harness.

[0004] In view of the above, the present invention designs a wire harness processing and cutting device, which solves the above-mentioned technical problems. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the present invention aims to provide a wire harness processing and cutting device that solves the problem of...

[0006] When cutting wire harnesses, both ends need to be fixed before cutting, which can cause the copper wires inside the wire harness to be stretched due to tension or cause burrs on the cut surface, resulting in a decrease in the processing quality of the wire harness.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a wire harness processing and cutting device, comprising a base, a collection chamber slidably disposed on the base, and support plates symmetrically disposed on both sides of the base. Multiple mounting slots are arranged in a circular array on one side of the support plate. The device further comprises: multiple sets of wire harness clamping components disposed within the mounting slots; a cutting component corresponding to the wire harness clamping components and disposed on one end of the support plate near the guide cover; a guide cover disposed in the middle of the two support plates and fixedly connected to a support plate without mounting slots on one side; and a traction component disposed inside the guide cover, with a guide post penetrating through the middle of the traction component. Both ends of the guide post are connected to the two support plates, and a telescopic component for controlling the movement of the traction component on the guide post is disposed on one side of the traction component, with one end of the telescopic component fixedly connected to the traction component. When the wire harness is being cut, the traction component clamps the wire harness, and the telescopic component drives the traction component to move on the guide post to control the length of the wire harness.

[0008] Preferably, the guide cover is in the shape of a "plum blossom" and has a hollow structure. A through groove is provided at the bottom of the guide cover. Each end of the "plum blossom" shaped guide cover is provided with a guide rail, and the length of the guide rail is the same as the length of the guide cover. A slider is provided on the guide rail, and the slider is driven to reciprocate on the guide rail by a traction component.

[0009] Preferably, the wire harness clamping component includes clamping blocks and connecting springs. Clamping blocks are symmetrically arranged in multiple mounting slots, and the clamping blocks are fixedly connected to the inner wall of the mounting slots through connecting springs. Each clamping block has an arc-shaped groove for transitioning the wire harness.

[0010] Preferably, the slider has a rectangular groove, and a compression spring is provided in the rectangular groove. One end of the compression spring is fixedly connected to the bottom end of the rectangular groove, and the other end of the compression spring is connected to a traction block.

[0011] Preferably, the cutting component includes a fixing block, a cutting blade, and a V-groove. The fixing block is provided on the side of the mounting groove near the guide cover, and the cutting blade is provided on one side of the fixing block. The cutting blade can be driven to reciprocate on the support plate by a driving device. Both the fixing block and the cutting blade are provided with inclined surfaces and V-grooves. By cooperating with the inclined surfaces on the fixing block and the cutting blade, the wire harness can be cut evenly under the limitation of the V-groove.

[0012] Preferably, the traction assembly includes a rotating disk, a fixed disk, and clamping rods; the rotating disk is rotatably mounted on a guide post, and has a drive groove arrayed in a ring on the rotating disk, with a driven gear ring coaxially mounted on the rotating disk; the fixed disk is mounted on one side of the rotating disk, and is slidably mounted on the fixed disk and the guide post, with multiple limiting grooves on the fixed disk, and clamping rods slidably mounted in each limiting groove; the clamping rods are slidably mounted in the limiting grooves, with an adjusting element at one end and a limiting post at the other end, the limiting post being slidably mounted in the drive groove; wherein, a drive motor is mounted on one side of the fixed disk, and the output end of the drive motor is connected to a drive gear, the drive motor driving the drive gear to rotate the rotating disk with the driven gear ring.

[0013] Preferably, the adjusting component includes a fixing spring and a connecting plate. One end of the clamping rod has a through groove, and the other end of the clamping rod is provided with a connecting plate. The connecting plate is connected to the clamping rod through the fixing spring.

[0014] Preferably, the traction block, the slider, and the connecting plate are all provided with arc grooves. The connecting plate cooperates with the arc grooves on the slider through the arc grooves, so that the wire harness is clamped between the connecting plate and the slider.

[0015] The beneficial effects of this invention are:

[0016] 1. The present invention provides a wire harness processing and cutting device. This device uses a wire harness clamping component and a traction component in cooperation. When cutting the wire harness, the wire harness is inserted into the guide cover. At this time, the traction component is driven by a drive motor to unfold. The adjusting component at one end of the clamping rod fits the wire harness. When the traction component is fully unfolded, the wire harness is clamped between the adjusting component and the slider. The telescopic component drives the traction component to move on the guide column to control the length of the wire harness to be cut. After the length is determined, the wire harness is cut by the cutting blade. Since the adjusting component can move slightly at one end of the clamping rod, the phenomenon of the two ends of the wire harness being fixed during cutting is avoided. This avoids the phenomenon of the copper wire inside the wire harness being stretched due to tension or the appearance of burrs on the cut surface of the wire harness, thereby improving the overall processing quality of the wire harness.

[0017] 2. The present invention provides a wire harness processing and cutting device. This device uses a wire harness clamping component and a cutting component. When the wire harness is inserted into the guide cover, the clamping block has an arc-shaped groove, and the two ends of the arc-shaped groove are fixedly connected to the inner wall of the mounting groove through connecting springs. When the wire harness is inserted, it can press the connecting spring against the inner wall of the mounting groove. At this time, the clamping block can fit against the surface of the wire harness. When the traction component is unfolded, the wire harness fits against the surface of the slider. Then, when the telescopic component drives the traction component to move on the guide column, the clamping blocks on both sides can limit the wire harness as the traction component moves. The movement of the traction component can straighten the wire harness and prevent the wire harness from bending, which would cause the cut wire harness to not meet the length requirements, thereby reducing the processing quality of the subsequent wire harness.

[0028] refer to Figures 1 to 7 As shown, a wire harness processing and cutting device includes a base 1, on which a collection chamber 14 is slidably disposed. Support plates 11 are symmetrically arranged on both sides of the base 1. Multiple mounting slots 111 are arranged in a circular array on one side of the support plate 11. The device further includes: multiple sets of wire harness clamping members 2, each set within a mounting slot 111; a cutting member 4, corresponding to the wire harness clamping members 2, positioned at one end of the support plate 11 near a guide cover 13; and a guide cover 13, positioned in the middle of both support plates 11, and positioned in relation to a guide cover 13. The support plate 11 without the mounting slot 111 is fixedly connected; the traction component 5 is set inside the guide cover 13, and the guide post 12 is provided through the middle of the traction component 5. The two ends of the guide post 12 are respectively connected to the support plates 11 on both sides. The traction component 5 is provided with a telescopic member 3 on one side for controlling the movement of the traction component 5 on the guide post 12, and one end of the telescopic member 3 is fixedly connected to the traction component 5; wherein, when the wire harness is cut, the traction component 5 clamps the wire harness, and the telescopic member 3 drives the traction component 5 to move on the guide post 12 to control the length of the wire harness.

[0029] Specifically, the guide cover 13 is in the shape of a "plum blossom" and has a hollow structure. The bottom of the guide cover 13 has a through groove. Each end of the "plum blossom" shaped guide cover 13 is provided with a guide rail 131, and the length of the guide rail 131 is the same as the length of the guide cover 13.

[0030] Specifically, the wire harness clamping member 2 includes clamping blocks 21 and connecting springs 22. Clamping blocks 21 are symmetrically arranged in multiple mounting slots 111, and the clamping blocks 21 are fixedly connected to the inner wall of the mounting slots 111 through the connecting springs 22. Each clamping block 21 has an arc-shaped groove 211 for transitioning the wire harness.

[0031] Specifically, a rectangular groove 133 is provided on the slider 132, and a compression spring 134 is provided in the rectangular groove 133. One end of the compression spring 134 is fixedly connected to the bottom end of the rectangular groove 133, and the other end of the compression spring 134 is connected to a traction block 135.

[0032] Specifically, the cutting component 4 includes a fixing block 41, a cutting blade 42, and a V-groove 43.

The cutting blade 42 can be driven to reciprocate on the support plate 11 by a driving device. Both the fixing block 41 and the cutting blade 42 are provided with inclined surfaces and V-grooves 43. By cooperating with the inclined surfaces on the fixing block 41 and the cutting blade 42, the wire harness can be cut evenly under the limitation of the V-groove 43.

[0033] Specifically, the traction assembly 5 includes a rotating disk 51, a fixed disk 52, and clamping rods 53; the rotating disk 51 is rotatably mounted on the guide post 12, and has a ring of drive grooves 511 arranged on it, and a driven gear ring 512 is coaxially mounted on it; the fixed disk 52 is located on one side of the rotating disk 51, and is slidably mounted on the guide post 12, and has multiple limiting grooves 524 on it, with clamping rods 53 slidably mounted within each limiting groove 524. A clamping rod 53 is slidably disposed in a limiting groove 524. One end of the clamping rod 53 is provided with an adjusting member 532, and the other end of the clamping rod 53 is provided with a limiting post 531. The limiting post 531 is slidably disposed in a driving groove 511. A driving motor 521 is provided on one side of the fixed disk 52, and the output end of the driving motor 521 is connected to a drive gear 522. The driving motor 521 drives the drive gear 522 to drive the rotating disk 51, which is provided with a driven gear ring 512, to rotate.

[0034] Specifically, the adjusting component 532 includes a fixing spring 5321 and a connecting plate 5322. One end of the clamping rod 53 has a through groove, and the other end of the clamping rod 53 is provided with a connecting plate 5322. The connecting plate 5322 is connected to the clamping rod 53 through the fixing spring 5321.

[0035] Specifically, the traction block 135, the slider 132 and the connecting plate 5322 are all provided with arc grooves 5323. The connecting plate 5322 cooperates with the arc grooves 5323 on the slider 132 through the arc grooves 5323, so that the wire harness is clamped between the connecting plate 5322 and the slider 132.

[0036] Working principle and process: Before starting work, the operator first inserts the wire harness into the mounting groove 111 on the support plate 11 through the external guide device. When the wire harness is inserted into the mounting groove 111, it pushes the clamping blocks 21 on both sides against the connecting spring 22 on the inner wall of the mounting groove 111. When the wire harness is fully inserted into the mounting groove 111, the clamping blocks 21 on both sides will fit against the circumferential surface of the wire harness. At this time, the drive motor 521 drives the drive gear 522 to rotate. The rotation of the drive gear 522 drives the driven gear ring 512, which meshes with it, to move synchronously. Since the driven gear ring 512 is coaxial and in contact with the rotating disk 51, the rotating disk 51 rotates with the rotation of the driven gear ring 512. The rotation of the rotating disk 51 passes through the drive groove. 511 drives the limiting post 531 on the clamping rod 53 to move in the drive groove 511, thereby causing the clamping rod 53 to move in the limiting groove 524 opened on the fixed plate 52, and then causing multiple clamping rods 53 to unfold in the guide cover 13. The unfolding of multiple clamping rods 53 pushes the wire harness to fit with the slider 132. After the wire harness is clamped, the telescopic member 3 drives the fixed plate 52 to move on the guide post 12 to adjust the length of the wire harness to be cut. Due to the arc-shaped groove 211 opened on the clamping block 21, when the fixed plate 52 moves and drives the wire harness to move, the other end of the wire harness slides in the arc-shaped groove 211, thereby avoiding the wire harness from sliding on the clamping block 21 for a long time and the phenomenon of the corner of the clamping block 21 breaking the wire harness, thus ensuring the quality of the wire harness cutting.

[0037] After the wire harness length is controlled, the cutting blade 42 is moved by the fixed block 41 and the cutting blade 42 set on one side of the mounting slot 111, driven by the driving component (not shown in the figure). The cutting blade 42 and the inclined surface and V-shaped groove on the fixed block 41 cooperate to make the wire harness cut evenly, avoiding the phenomenon of burrs or bevels on the cut surface of the wire harness. During cutting, one end of the wire harness is fixed in the arc groove 5323 set on the connecting plate 5322 and the slider 132. When the cutting blade 42 cuts, the stress generated by the wire harness will pull the connecting plate 5322 towards the cutting blade 42, thereby avoiding the stress caused by fixing both ends of the wire harness, which would cause the internal copper wire to be stretched or even broken, affecting the performance of the wire harness. Therefore, the present invention adopts a micro-motion method at one end to release the stress during cutting, thereby avoiding the problem of the internal copper wire being stretched or broken.

[0038] After the wire harness is cut, the reverse rotation of the drive motor 521 drives the clamping rod 53 to move within the limiting groove 524 set on the fixed plate 52, thereby causing multiple clamping rods 53 to retract inward. When the wire harness is no longer clamped, the cut wire harness will slide down along the inner wall of the guide cover 13 into the collection chamber 14, thus completing the collection of the wire harness.

[0039] When cutting smaller diameter wire harnesses, the clamping rod 53 pushes the wire harness to the traction block 135. The wire harness is fixed by the clamping of the connecting plate 5322 and the traction block 135. At the same time, the rotating disk 51 continuously pushes the clamping rod 53 to completely clamp the wire harness between the traction block 135 and the connecting plate 5322, thus completing the fixation of the wire harness. Therefore, the arc groove 5323 on the traction block 135 needs to be smaller than the arc groove 5323 on the connecting plate 5322, so that it can adapt to wire harnesses of various diameters and improve its applicability.

[0040] The above embodiments are merely exemplary embodiments of the present invention and are not intended to limit the present invention. The scope of protection of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to the present invention within the scope of its essence and protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of the present invention.
